Mercedes-Benz is reconfiguring the S-Class family with two versions which seem to be more fuel-efficient, with a yet not confirmed news for a launch in the US.

We are talking about the fresh S300 BlueTEC Hybrid and the S350 BlueTEC 4Matic, the latter possibly to arrive as a replacement for the previous generation.

First, the S300 BlueTEC Hybrid is the most expected hybrid, coming with a 2.2-liter four-cylinder turbodiesel engine, backed up by an electric motor, positioned between the engine and the transmission.

The engine develops 204 horsepower alone, with an additional of 26 horsepower from its electric motor. Unlike the 500 Plug-in Hybrid, this model can`t drive the vehicle on its own, but it assists the engine instead when the vehicle is accelerating.

Second, we are talking about the S350 BlueTEC 4MATIC, featuring a 3.0-liter V6 turbodiesel, mated with a 4MATIC all-wheel-drive system.

In terms of power, the S350 BlueTEC 4MATIC produces 258 horsepower and 457 pound-feet of torque, with a fuel economy of around 40 mpg for the European combined cycle.

We don’t know exactly when the models will hit the US market, but we do know that the S350 BlueTEC 4MATIC will be displayed at the local showrooms as the 2015 model.
